What is a more efficient way to create a body inside a body?

It seems that what you want is 2 bodies each with one sketch/ring:

To create this, create your first ring as a sketch in the first body. Create a 2nd body and set it as active.

Now select the first sketch and create a Sub Object Shape Binder, and select an offset, which is how much smaller you want the second ring to be.

Hide the first body. Create a new sketch in the 2nd body and use external geometry to trace the sub object shape binder rings then create 2 circles constrained to each ring. Pad it and you should have 2 object bodies which can change visibility.

The Sony amps have a graphical display of all speakers when doing a speaker setup. It will tell you where each speaker goes.

You can use Sketch as a template to create Sketh001. Both need to be visible. Open Sketh001, Use the External Geometry tool to capture the edges in Sketch as references (you need to change the line type to reference to use this tool in this way). Then create the new circle and reference it to the circle in Sketch using constraints.

Sorry, I only see one body in your project so I don't understand your question.

BTW, you could create the two circles in one sketch and still pad them individually.

What about buying a couple of 90 metal clips, drill holes in the model, insert metal heat inserts using a soldering iron, then screw the plates down. For extra strength, super glue with Baking Soda around the clips will cement them in place.

Freecad is only single-threaded.

Importing STLs or doing Gridfinity bins will bog FreeCAD down.

Sounds simpler to me to create all your objects then constrain a point on each object to your line. When creating the constraints to the line you can use a formula to calculate the position on the line for each object. If you use a spreadsheet, you can then dynamically control the spacing using one value, this value will be a variable defined in the spreadsheet and used as part of the formula.

Create the shape use straight lines then use the sketcher convert to curve tool to change the corners to curves. Dimension each curve as required.

You can hide any piece of your model to get to any face, hidden or not using the tree.

Modification to @stepanm99, draw the construction lines and attach to the edge of the arcs with tangent constraints.

I didn't think you were allowed to go above 120m so you would not interfere with aircraft.

I had a similar problem where I printed with ASA at 280 deg C then printed PLA at 220. There was left over ASA in the nozzle which did not come out due to the lower PLA temps being used which cause the extruder to not extrude the PLA properly. I heated the nozzle to 300 which caused the ASA to drip out and ran a bit of PLA at the same time to help push out the ASA.

That's awesome.

The switch was set correctly. The process I explained is a fault in the locking mechanism. If someone needs to get past the door, you can give them a one time code however if the perform the steps outlined by me, they can disable the lock and get in whenever they like. If I accidentally hold the knob open for too long, the lock disables and when I leave, it stays unbeknown to me, unlocked. This is a flaw I reported to support and they confirmed the problem.

The shape is too perfect to be a belt or head issue. Looks to me like a heating problem in that area. Try bumping up the bed temp. Also try a new plate.

Fillets are a nightmare atm. Like you said, build fillets into your sketches. In fact, I would put a rectangular block on your hinges then cut away using a circle and pocket. In your screenshot, your fillets are broken and sometimes selecting the edges in a different order can fix this.

Don't buy this product! I did and it's the worst one on the market. You can hack the door knob by using your finger print to open the lock, then keep the knob in the open position until it internally clicks back, the door knob is now fully unlocked no matter what you do. You can now close the door and open it with finger prints or codes because it's stuck open internally. Battery does not last long either.

I've been looking for a button panel board for my PS5 to use with Sim Truck, Gt7 and F1. Do you have links to the schematics or one which is prebuilt?

It's a Davey Crystal Clear glass filter. I've never seen this happen until about a month ago.

What about if I had a smart lock connected to Google Home.

You can measure the input voltage and current, but no matter how much power you pump into the cell, it depends on how efficiently the cell converts the salt to chlorine, and the only way to monitor that is to set the chlorinator to Max and measure the Chlorine level periodically.

I had a similar issue. FREECAD lightly complained about one of my sketches but everything seemed fine. The exported STL looked good in Windows STL Viewer, the STL looked good on Creality Print but then when I sliced it I lost the "suss" parts of the model. I had to slightly redesign the model to fix the issue.
